' r Application filed September 4, 1908. Serial No. 451,692.

county of Kings and State of New York,

have invented certain new and useful. Imf provements in Paer,-Feedingl\lachine Attachments, of whic the following is aspecification.

The resent invention relates to improvements in that classof machineswhich is designed to feed'successively. one sheet of paper at a timefrom a pile to a' printing press, paper folding or ruling machine, orother Inachin'es designed to operate upon paper.

More particularly, the invention relates to that class of feedingmachines which carries a stack of sheets of paper or the like upon asubstantially horizontal table, and from which the sheets are fed by thefeeding mechanism unto the feed table.

In order to maintain and hold the other.

sheets of a ile in fixed and proper positions as the top seet is beingso arated therefrom,

holders are provided usua y, which assure to some extent the separationof but a single sheet of paper from the pile by resting upon the sheetsunder the top sheet as the top sheet is being removed. Suchholdersconsisted, heretofore, usually of a single contact block, and it will becasily'seen that, when the sheets of paper'are held only at a singlepoint, the same may be easily brought out of their proper positions bythe sheet advancing means; for instance, the advancing means may,although not carrying the same in the direction of their own travel,force the sheets sideward. On the other hand, since the rear edges ofthe sheets of paper do not coincide as the same are combed, the contactblock, heretofore in ,use, will from time to time allow two sheets to befed unto the feeding table if not adjusted with particular accuracy.

It is now the object of the present'invention to provide means, wherebythe aforesaid defects of the feeding machines are obviated.

To attain this end, the device consists of a plurality of fingers,engaging the stack of paper but caused to be disengaged with the sameimmediately before the top sheet is being removed;"as-now the top s eetis being advanced, the fingers engage in. succession the remainingsheets and always at the small est possible distance beyond the topsheet, whereby, first, the sheets under that top sheet are prevented intheirforward movement, and, second, their proper position is assured.

Other objects of the invention will be apc parent from a reading of thespecification and an examination of the drawin s, forming p art of thepresent application for ette'rs'Patent.

The invention 1s illustrated in the accompanying drawings, in whichFigure 1 is a side elevation of a paper feeding machine having'theattachment, forming the subject matter of the present application forLetters Patent, and Fig. 2 is a side elevation on line 2-2 of Fig. l, onan enlarged scale.

It will be observed that in Fig. 1- of the drawings only those parts ofthe feeding machine are shown which are necessary to understand theoperation of the improved paper feeding device, which can obviously beattached to a paper feeding machine of any suitable construction,whereby the paper is being fed from a pile to a machine designed tooperate upon paper.

In the drawings, 3 indicates one of a pair of the side parts of theframe of the feeding machine, and 4 one of a pair of the uprights,between which and the transverse vertical wall 5 of the frame of themachine is arranged in any suitable manner a vertically movable table(not shown in the drawings), carrying the stack of paper indicated at 6.The transverse vertical wall 5 is provided at its upper end with aforwardly bent lip 7, unto which the sheets are fed by a feeding means8, actuated by the main shaft 9 of the apparatus, which main shaft isjournaled in the side frame 3 and operated by any suitable source ofpower, for instance, by the intermediary of a chain 10, meshing with asprocket wheel 11, mounted upon the main shaft 9. The mechanism fortransmitting motion from the main shaft 9 to the feeding roller 8 isimmaterial and is notvdescribed.

The sheets are fed from the forwardly bent lip 7 within reach oftransporting rollers 12 and -13, and thus unto the feed band 14, whichbring the same, in a well known manner, unto the cylinder of the pressor to any other suitable apparatus or machine. The

' apparatus thus far described does not differ in any essential way fromthe feeding machines heretofore m use.

The paper retaining or holding device,

forming the subject matter of the present application for LettersPatent, is adjustably mounted on a bar 15, arranged arallel to the planeof the top sheet'of the p' e of-paper and at right angles to the mainshaft 9 of the apparatus. This bar is mounted in the brackets 16 and 17,attached to the side frame3 and .the up ght 4,"reslpectively, andcarries the frame..18 of the s eet retaining device,

1 which frame is provided with upwardly extending extensions 1:) and20,' which engage {the-shaft 21, arranged parallel with the bar 15 andat right angles to the shaft 9. The

. shaft 21 is rotatably mounted in bearings 22 rprovided with a hole26,.fitting the station-- and 23, carried by the-frame 3 and. theupright 4, respectively, and is provided at its inner end with a bevelgear 24-, in mesh with a similar gear 25, mounted upon the main shaft9'. The purpose of this arrangement will be hereinafter'more fullydescribed.

The frame of the paper retaining device is my bar 15 and allowing of asliding movement of the frame relative to the bar,when

.it becomes necessaryto adjust the position.

of the frame upon said bar. serves to secure the frame upon the shaft inthe desired adjusted position. The frame 18 is furthermore provided witha slot 28, at

right angles to the plane of the paper, covered by an upper plate 29 anda lower plate 30,

i suitably attached to said frame and provided with holes 31 and 3:2,res ectivcly, which holes are engaged by the ho ding or retainingfingers33. The fingers are slidably arranged in the plates 29 and 30,between which are arranged springs 34, each encircling one finger andbearing against the plate 29 and the lower enlarged end 35 of thefingers, tending tokeep thus said fingers in their lower positions. Thelower end of the fingers may be provi ed with frictional shoes 36, madeof resili t ate'rial, such as rubber. The upds df the --fingers areprovided with flanges 37, limiting the downward movement of the fingers,which are pivotally connected with two-armed levers 38, carried by.

gfour'c'ams 41 mu t be provided. -These cams are arranged-on a sleeve42, which is secured by means of a key 43 to the shaft 21.

lifted simultaneou'sly, but are brought in contact with the papersheets'successively;

mentioned hereinbefore, the fingers are the cams 41 are, therefore, asshown in the A set screw 27 drawings provided with acting faces ofdifferent lengths.

The rearedge of the frame 18 is provided with a finger 44, contactingwith the rear edges of the sheefii of paper and determining thereby theprdper position of the fingers 33 upon the machine.

The operation of the device is as follows: The main shaft 9 of the aparatus operates the feeding means 8 and a so the retaining means orfingers 33 in unison motion. More articularly, the earns 41 shift thetwo-armed evers 38, whereby the fingers 33 are lifted against thetension of the springs 34, immediately before the feeding device 8starts to, The top sheet is advance the top sheet. thereby free to move.forward. As shown in the drawings, the fingers I, II, III and IV areactuated by the cams I, II, III and IV,- respectivelyl As the sheet ismoved by the feeding mechanism 8 toward the transporting rollers 12 and13 and beyond the edge of the shoe 36 of the finger I, its correspondingroller 40 slides down the incline of the cam I, whereby its spring 34causes the finger to contact with the sheet next to the top sheet,holding thereby thissheet from movement. As the top sheet is advancedfurther by the feeding means 8, the fingers II, III and IV are one afterthe other disengaged with their corresponding cams and brought by theirrespective sprin s in contact withthe sheet next to the top s eet.Attention is called to the fact that the cams are arranged upon theshaft 21 in such a manner, that the finger IV engages the sheet next tothe top sheet immediately' before the top sheet comes within the reachof the transporting rollers 12 and 13. It-will be observed thatthus thesheets under the top sheet are'held at a plurality of points,maintaining and holding thereby-the same in a fixed and proper positionand assuring thus practically the separation of but a single sheet ofaper. If, however, the sheets are comber as shown in Fig. 1 of thedrawings, 'each finger will hold one or more sheets under the top sheetin a fixed position, depending upon the relative position of saidsheets.

Obviously, it will be necessary to adjust the positions of the cams and"the frame 18 upon the machine, as different sizes ofpaper are placedupon the paper carrying table. For this purpose the key seat 43 in theshaft 21 may be extended throughout the whole length of theshaft 21, orthrougha portion of four fihg'ers 33' the same according to therequirements.
